archangel88,
This is a good question, but we do not neen to guess, the Bible tells us clearly.
Jesus stated this very clearly at John 8:44. In the 13th chapter of Matthew, Jesus gave an illustration about the sowing of the SEED. The good seed would turn out to be the sons of the kingdom, the bad seed to be sons of Satan, the Devil, Matt 13:36-39.
The evil one is identified again by Jesus at Rev 12:9.
Paul said that Satan is the God of this world, 2Cor 4:3,4.
Jesus said that Satan is the ruler of this world, John 12:31, 14:30, 16:11.
John said that the whole world is lying in the power of the wicked one, 1John 5:19.
It is worth reading the interchange between Jesus and Satan just after Jesus was baptized. Notice Luke 4:5-8, where Satan offered Jesus all the Kingdoms of the world, and their glory, if he would do an act of worship to him. Notice that Jesus did not say that the Kingdoms did not belong to Satan, but only that it is to God alone that we should render sacred service.
Theology today, has a name for the trouble we are having . It is called Pansatanism, which means that the world today is manifesting the personality of it's god, Satan.
One thing is sure, if this world were ruled by God, or Jesus, we would not have the troubles we are facing today.
